Factors Associated with Pre-Dental Students’ Intention and Willingness to Serve in the Underserved Community and Vulnerable Population
Abstract
:1. Introduction
2. Materials and Methods
- Demographics and Characteristics: Participants’ age, gender, race, ethnicity, yearly family income, current educational status, undergraduate institution, undergraduate study major, and whether they were first-generation college students, and those from an underrepresented minority, or from disadvantaged or rural backgrounds were included.
- Past Experience in Access to Dental Care (4 questions): Participants were asked whether they had a previous difficult experience in getting a dental appointment or finding an available dentist when needed, financial difficulty in affording dental care, transportation difficulty in getting to a dental office, and whether they had experienced difficulty in receiving dental care due to language barriers. Answer choices were “Yes” (1 point) or “No” (0 points).
- Psychosocial Factors (Table 1):
- Knowledge (1 question): Participants were asked how much they agree with the statement “Dental caries is the most common chronic disease in children.” Answer choices were Strongly Agree, Agree, Disagree, and Strongly Disagree. The responses were then dichotomized and scored as “Strongly Agree” (1 point) and “Less than Strongly Agree” (0 points). Participants who answered “Strongly Agree” were considered as having higher knowledge of the prevalence of dental caries among children than those who had “Less than Strongly Agree.”
- Confidence (1 question): Participants were asked how much they agree with the statement, “I believe I can make an impact in reducing oral health disparities in my community.” Answer choices were Strongly Agree, Agree, Disagree and Strongly Disagree. The responses were then dichotomized and scored as “Strongly Agree” (1 point) and “Less than Strongly Agree” (0 points). Participants who answered “Strongly Agree” were considered to have higher confidence in making an impact in the community compared to those who had “Less than Strongly Agree.”
- Attitude (2 questions): Participants were asked how important it is for them to address these issues as future dentists: “Access of dental care in underserved, vulnerable and rural communities” and “Access to dental care for children.” Answer choices were Very Important, Important, Slightly Important, and Not Important. Participants who answered “Very Important” for both questions (1 point) were considered as having a higher attitude towards addressing access to dental care issues compared to those who had “Less than Very Important” (0 points).
- Previous Volunteer Behavior (2 questions): Participants were asked when they had the opportunity in the past, how often they had “Volunteered for an underserved community” and “Volunteered for children.” Answer choices were Always, Often, Sometimes, Never. Participants who answered “Never or Sometimes” for both questions were considered having lower volunteer behavior (0 points), and those who answered “Always or Often” for at least one question were considered having a higher volunteer behavior (1 point).
- Intention to Serve the Underserved and Vulnerable Populations (4 questions): Participants were asked, when they become dentists in the future, how likely are they do the following: “Serve children,” “Serve vulnerable populations,” “Serve underserved populations,” and “Practice in underserved communities.” Answer choices were Very Likely, Likely, Unlikely, and Very Unlikely. Participants who answered “Very Likely” to all 4 questions were considered to have a higher intention to serve the underserved and vulnerable populations (1 point) compared to those who answered “Less than Very Likely” (0 points).
3. Results
- Participant Characteristics: Participants from underrepresented minority, disadvantaged background, rural residential background were all significantly associated with higher intention to serve the underserved and vulnerable populations (p = 0.006, 0.015, 0.013, respectively) (Table 3). Although not statistically significant, first-generation college students also reported higher intention to serve such populations with nearing significance (p = 0.057). Regression analyses revealed no statistical difference in the outcome by gender or race.
- Past Experience in Receiving Dental Care: Having difficulty in getting a dental appointment or finding an available dentist when needed was significantly associated with higher intention to serve the underserved and vulnerable populations in the future (p < 0.001) (Table 3). Previous experience of having difficulty in receiving dental care due to financial reasons, transportation to the dental office and language barriers were also associated with higher intention to serve the underserved and vulnerable populations as a future dentist (p = 0.005, 0.007, 0.003 respectively).
- Psychosocial Factors: Participants’ knowledge on the prevalence of dental caries among children, confidence in making an impact in the community, attitude towards addressing access to dental care issues, and previous volunteer frequency were all highly correlated with higher intention to serve the underserved and vulnerable populations as a future dentist (all p < 0.001) (Table 3).
- Participant Characteristics (Model 1): Participants from a rural residential background, compared to non-rural residential background participants, were 1.7 times more likely to have higher intention to serve such populations (OR = 1.73, 95% CI = 1.1–28.66). The model has an adequate overall goodness of fit (Hosmer-Lemeshow test, Chi-square = 3.45, p = 0.90) with Nagelkerke R square of 0.15.
- Participant Characteristics + Past Experience in Receiving Dental Care (Model 2): Participants who have past experience of difficulty in getting a dental appointment or finding an available dentist when needed were found to be a strong predictor for having higher intention to serve the underserved and vulnerable populations (OR = 1.45, 95% CI = 1.22–14.83). The model presents a good overall goodness of fit (Hosmer-Lemeshow test, Chi-square = 2.87, p = 0.94) with Nagelkerke R square of 0.28.
- Participant Characteristics + Past Experience in Receiving Dental Care + Psychosocial Factors (Model 3): Higher attitude towards addressing access to dental care issues and higher confidence in making an impact in the community were found to be the strongest predictors for higher intention to serve the underserved and vulnerable populations (OR = 2.78, 95% CI = 2.60–98.96 and OR = 2.60, 95% CI = 1.24–147.47 respectively). Higher knowledge on the prevalence of dental caries among children was also a predictor of higher intention (OR = 1.34, 95% CI = 1.04–13.89). The model has an adequate overall goodness of fit (Hosmer-Lemeshow test, Chi-square = 4.91, p = 0.77) with Nagelkerke R square of 0.53.
4. Discussion
5. Conclusions
- Participants’ demographics and characteristics are strong determinants of future intent to serve underserved communities and vulnerable populations.
- Personal experiences of difficulties in dental care access and past volunteering experience in underserved communities and working with vulnerable populations have a significant influence on participants’ intent to serve such populations and communities.
- Attitude, confidence, and knowledge appeared to be strong predictors among participants’ future intent.
